A suitable choice is the STM32WLE family, which integrates a low-power STM32 microcontroller core with built-in LoRa transceiver. For instance, you might consider:
Key benefits:
- Built-in LoRa transceiver (no separate LoRa chip needed).
- Ultra-low-power modes ideal for battery-based or low-power designs.
- Seamless integration of sensor reading and data transmission at low duty cycles (1Hz).
